QXL/Spice KMS Driver
Summary
Currently the QXL driver is X.org only, a KMS driver is required to move forward with projects like spice 3D, and also to allow more features to be show in virt environments like plymouth.
Owner
- Name: Alon Levy
- Email: <alevy@redhat.com>
Current status
- Targeted release: Fedora 18
- Last updated: 7-24-2012
- Percentage of completion: 50%
Detailed Description
The current spice GPU driver for Linux guests is an X.org only driver. A kernel modesetting driver needs to be developed along with a new X.org driver that runs on top of it.
Benefit to Fedora
Fedora acts closer to native hardware inside spice VMs.
Scope
- Develop a basic modesetting driver for QXL GPU
- Develop an acceleration/memory management interface for QXL GPU.
- Develop a new X.org driver on top of the new interfaces.
How To Test
- Test inside a virtual machine with QXL support, via virt-manager: create a new vm with qxl video (default of 64MiB) and spice.
- plymouth should show up along with smooth booting.
- X should work as usual.
User Experience
- There should be no regressions from the non kms driver experience.
- If the qxl module isn't loaded (compiled out or forced not to load via kernel command line) driver should work as usual without kms.
- Older drivers will not be supported when kms module is loaded. Fedora will update the kernel side by side with xf86-video-qxl so this won't be a problem.
Dependencies
- kernel changes - drivers/gpu/drm/qxl
- X.org changes - updated xf86-video-qxl
Contingency Plan
Do nothing, stay as we are now.
Documentation
See spice-space
Release Notes
Fedora 18 now ships a new qxl kernel driver that supports kernel mode setting.
